*CPI Score relates to perceptions of the degree of corruption as seen by business people and country analysts and
ranges between 10 (highly clean) and 0 (highly corrupt).

**Confidence Range provides a range of possible values of the CPI score. This reflects how a country's score may vary,
depending on measurement precision. Nominally, with 5 percent probability the score is above this range and with another 5
percent it is below. However, particularly when only few sources are available an unbiased estimate of the mean coverage probability
is lower than the nominal value of 90%.

***Surveys Used refers to the number of surveys that assessed a country's performance. 12 surveys and expert assessments
were used and at least 3 were required for a country to be included in the CPI.
